5 Claims.

My invention relates to the typewriter ribbon r -conditioning and re-inking devices and more particularly to such applicators which are adapted for i e-conditioning said ribbon in the typewriter machine, without removing same from its position.

Accordingly an object of my invention is to provide said typewriter machine with a suitable ribbon re-inking means comprising a housing which is provided with a suitable ink retaining cartridge means, which when in position, it will permit said typewriter ribbon to function normally while it passes from one spool to the other during the operation of the machine, also to coat the surface of said ribbon, at one or either of its sides, and automatically covering its other side with a light coating of an ink when rolled upon a ribbon spool, thereby increasing and prolonging the durability and the flexibility of said ribbon and also increasing its usefulness and preventing its deterioration.

Another object of my invention is to provide a suitable ribbon re-inking device which is especially adapted for re-inking and for reconditioning said ribbons of the typewriter machine or the like, and which in its construction comprises a suitable housing means adapted for receiving and for holding therein a suitable cartridge means, said housing means having a set of prongs for forming a set of suitable gripper means which are adapted for holding and for maintaining said housing means in its position and close to the ribbon spool cage, so that one of the surfaces of the passing ribbon will come, at all times, in contact with the extended end surface of said gripper extensions, which is applicable to the Royal typewriter machine.

Fig. 4 shows the top view of the re-inking apparatus shown attached to the Royal" typewriter machine and showing the position of the ribbon member when in operation.

Fig. 5 shows the form of a blank of the reinking attachment, which is used in all types of tyepwriter machines, out of which the re-inking apparatus is formed, showing the operation number 1.

' tridge showing the position of the spring clip cartridge means, said cartridge means being in terchangeable and renewable and is charged or saturated with a suitable ink, thus permitting said ribbon, while its surface passes thereover, to be coated with said ink and thereby causing said ribbon to gradually absorb some of it during the operation of said typewriter machine. 1

Reference now is had to the accompanying drawing, in which the similar reference characters denote the similar parts.

In the drawing:

Fig. 1 is the perspective view of the re-inking attachment shown in position and attached to the Underwood typewriter machine, also showing the position of the ribbon when in operation.

Fig. 2 is the end elevational view.of the reinking attachment, taken in the direction of the arrows 2-2, of the Fig. 1.

Fig. 3 shows the perspective view of another which holds the rolled layers of the cartridge in position, taken on the line 89 of the Fig. 8.

Describing my invention more in detail, in its broader aspects, said invention comprises a reinking device as shown in Figs. 1 and 2, which is particularly adapted for and to the Underwood typewriter and which is made entirely out of one piece of material, the blank of which is shown in Fig. 5.

Said device comprises a plate member I which is provided with a center member 2 for forming the bottom section 4, while the center is provided with a hole 6 to provide air or ink circulation when the housing plate 8 is formed cylindrically,

type attachment showing altered prong and having a longitudinal throat 40 disposed thereover, as shown.

The outermost section II) of said housing plate 8 is provided with a suitable tongue extension member 12 Which is adapted for holding a cartridge member I4 in place, as shown in Figs. 1 and 2, and which is also for the purpose to prevent said cartridgemember Hi from slipping or vided with a downward bent as at 20 and then parallel to the gripper section II for forming a suitable ledge members, of which, the outer ledge members 22 are lower in their respective positions, while the center ledge member 24 is slightly higher, as shown in Fig. 2, and in addition, said outer ledge members 22 are provided with an upwardly extending ends 88 which terminate with a suitably curved ends 28, while said center ledge member 24 is provided with a downwardly extending end 88 terminating with a curved end 82, so that when said' re-inking device is placed in a position, said ledge member 24 including said ledge members 22 will straddle and will overlap the ribbon guide and release lever 84, shown in dotted lines, which is substantially a part or the tyepwriter machine, and the housing plate member 8 when in its position, will not interfere with the movements of the letter hammers and will hold said cartridge member ll with said extended end It in position and against said ribbon I1,

during the operation of said machine.

In the Figs. 3 and 4, said re-inking device is shown in one of the modified forms and is applicable for theme with a Royal" typewriter, comprising a housing plate'member 8 which is for the purpose to hold and retain therein the cartridge member I and for having its end member l8 extending sidewardly and outwardly therefrom, in order to engage the-surface of the ribbon I] while passing thereby, as shown in is substantially a part of the typewriter machine,

said grippers i8 are formed accordingly, in order to meet the required condition.

Therefore said gripper extending sections it are provided with adownward bent, as at 20 and then parallel to said gripper sections l8, of which, the center section 88 extends outwardly and terminates with a downward bent 4i, while the gripper extensions 42 are provided with an upward bent 84 having their ends 48 terminating with a hook end 88, and which are for engaging the rim section of said spool cage member 36, as shown.

It may be noted, that in said plate member I, the relative position of said sidewardly extending grippers Iii and a, plate member I out of which said housing plate 8 is formed, is at a suitable angle, see Fig. 5, so that by reversing said plate member i and then forming said housing plate 8 a suitable narrow throat 40 is formed and extends the entire length of said housing plate 8 and which may, due to such forming operation, be at one or the other side of said bottom section 4 and over the center member'l, through which said sidewardly extending end ii of said cartridge member It will pass, for engaging the surface of said ribbon i1, and thereby providing a right hand or the left hand inking device which may be applied to the respective side of the typewriter machine.

It may also be noted, that said grippers i8, as shown in Fig. 5, are universal in their respective positions, thus enabling one skilled in art to form same properly and thereby allowing same to be fitted to any conventional typewriter machine.

In the Fig. 6 is shown one form of bending and forming the housing member 8 and also for form ing same properly in relation to the center member 2, having therefor a suitably formed die 52 and a punch member 84, as shown in dotted lines, while in the Fig. 7 a suitable forming punch 56 and a forming die 88 is shown in dotted lines. which is used for completing the forming of said device as described and illustrated in the Figure 3.

In the Figs. 8 and 9 is shown a cartridge member H, which may, if so desired, be made out of suitable cloth, felt or the like, which is held in its rolled position by means of a suitable spring like ring member 60 and thus allowing said end member or applicator it to extend outwardly therefrom, as shown, so that by saturating said cartridge H with a suitable ink preparation, then only a small portion of said ink, through said end member l6 and its entire surface so exposed will be distributed and transmitted upon the surface of said typewriter ribbon II, without removing same from the machine and during its operation.

While I have thus described my invention with great particularity, it will be clear that the same may be modified throughout a wide range.

I accordingly do not propose to be limited to the exact details of construction herein shown on the drawing and described in the specification, but reserve the rights in practice to make the necessary changes and modifications therein, which may come within the scope of the appended claims.
